Since Slovenia declared independence in 1991, its Governments have underscored their commitment to improving cooperation with neighbouring countries and actively contributing to international efforts aimed at bringing stability to Southeast Europe. Resource limitations have nevertheless been a problem hindering the efficiency of the Slovenian diplomacy. In the 1990s, foreign relations, especially with Italy, Austria and Croatia, triggered internal political controversies. In the last eight years, however, a wide consensus has been reached among the vast majority of Slovenian political parties to jointly work in the improvement of the country's diplomatic infrastructure and to avoid politicizing the foreign relations by turning them into an issue of internal political debates.
Relations with neighbors Slovenia's bilateral relations with its neighbors are generally good and cooperative. However, a few unresolved disputes with Croatia remain. They are related mostly to the succession of the former Yugoslavia, including demarcation of their common border. In addition, unlike the other successor states of the former Yugoslavia, Slovenia did not normalize relations with the "Federal Republic of Yugoslavia" (Serbia and Montenegro) until after the passing from power of Slobodan Milošević; although the Slovenes did open a representative office in Podgorica to work with Montenegrin President Milo Đukanović's government.
Succession issues, particularly concerning liabilities and assets of the former Yugoslavia, remain a key factor in Slovenia's relations in the region. On the whole, no conflicts mar relations with neighbors, which are on a sound footing. Numerous cooperative projects are either underway or envisioned, and bilateral and multilateral partnerships are deepening. Differences, many of which stem from Yugoslavia's time, have been handled responsibly and are being resolved.
